If you overfed her for 3 weeks another 2 days won't make a difference.
I don't buy prepackaged raw so I don't know what the doses are.
For home made raw it's 2-3% of their adult weight.
The worst thing that would happen from over feeding is that she gains weight and then you have to feed less so she can lose it.
That's what they say, start with 2-3%, see how it goes and adjust it.
Did she gain weight (as in got fatter)? Lose weight? Stayed the same?
